- The movement of Earth currently in the Solar System is not currently orbiting the Sun.
- In the Solar System, the Sun is the largest object and has 1,048 times the mass of Jupiter.
- However, the gravitational pull which Earth exerts on the celestial body is exerted in the same or smaller amount on the planet.
- Kepler's third law describes the relationship between the masses of two objects mutually revolving around each other and the determination of orbital parameters.
- Earth orbits a barycentre and not exactly the Sun.
- Generally, the barycentre of the bodies in the Solar System is near the Sun.
- However, because of the mass, and influence of gas giants Jupiter and Saturn and orbits, it is rarely inside the Sun.
- Currently, the barycentre is outside the Sun and not inside it and hence, Earth is not currently orbiting it.
- So, the planet is revolving around a point in space and not the Sun.
- The Earth and Moon orbit a point which is 5,000 kilometres (3,100 miles) from the Earth's centre.
- However, this keeps changing as the Moon slowly moves away from the Earth.
